An international study led by researchers at McGill University has found that those with poor dental hygiene tend to experience more severe COVID-19 symptoms.

Using the digital medical and dental records from 568 Qatari patients with COVID-19, the researchers found that those with periodontitis, better known as gum disease, were more likely to suffer from COVID-19 complications.

Specifically, the patients were 3.5 times more likely to be admitted to the intensive care unit, 4.5 times more likely to require a ventilator and 8.8 times more likely to die from COVID-19 compared to those without gum disease.
